How can I convert a number to IEEE single precision?
I didn't see a good way in the documentation. Obviously this is a bad way:
(define (number->single-precision x)
(read (open-input-string (format "~Af0" x))))
(number->single-precision 2.0) ;==> 2.0f0
I want to do this because I am reimplementing an old C extension in pure
Racket code, and want to exactly mimic the C extension's behavior. The
C extension happens to sometimes produce Racket IEEE single precision
numbers like 2.0f0, but the pure Racket code will be working with
non-single-precision numbers like 2.0.
